While job seekers are increasinglyhunting for work on Facebook since most of them of course have a profile on the world's largest social network, new data shows they might be better off looking on LinkedIn (duh) and Twitter (hmm). In fact, LinkedIn networks still drive more views to job applications than their Twitter and Facebook networks combined.

48 percent of recruiters use LinkedIn exclusively. These recruiters have an average of 661 connections, and don't leverage the other two networks for social recruiting. From there, recruiters use Twitter more than Facebook. Despite the fact that recruiters have fewer connections on Twitter (37 followers on average), 19 percent are connected to both LinkedIn and Twitter, while only 10 percent are connected to both LinkedIn and Facebook (245 friends on average).

More specifically, for job applications, LinkedIn drives almost nine times more applications than Facebook and three times more than Twitter. Interestingly, a Twitter follower is almost three times more likely to apply to a job than a LinkedIn connection, and more than eight times more likely to apply than a Facebook subscriber. This would suggest that Twitter might be a highly underutilized social recruiting channel. Furthermore, recruiters' Twitter followings drive almost twice as many job views per job as their Facebook fan bases.

The data comes from recruiting software company Bullhorn, which analyzed the online activities of 35,000 recruiters. The full 18-page report, titled "The Bullhorn Reach Social Recruiting Activity Report" (PDF), offers insight into the usage of social media in recruiting, comparing the big three social networks: LinkedIn, Twitter, and Facebook. If you prefer a summary to the above infographic, here are some key findings:

LinkedIn drives more views per job than Twitter and Facebook, generating three times the amount of views of Twitter and six times the amount of Facebook.

Recruiters who post jobs on social networks are likely to receive more applications from LinkedIn, with the social network driving almost nine times more applications than Facebook and three times more than Twitter.

Looking at the relative number of applications per contact, a Twitter follower is almost three times more likely to apply for a job than a LinkedIn connection.

"If you are serious about finding a job, Facebook should not be your first stop. There is a huge disconnect between where people are looking for jobs and where they will actually find one - job seekers are focusing on Facebook, while recruiters are on LinkedIn," Bullhorn President and CEO Art Papas said in a statement. "There is no question that social recruiting works. Our goal is to help recruiters and job seekers develop new strategies for connecting the right employees with jobs and companies that fit."
